Engine on Models CH350 and 454XL. This kit is used with Sierra exhaust manifold 18-1929 (Starboard) and exhaust manifold 18-1933 (Port), giving boat owners a matched mounting solution for either side of the engine when installing or replacing exhaust manifolds. It is designed to pair with Manifold Gasket 18-0418, which seals the manifold-to-block joint once the mounting hardware from this kit is in place.\u003c\/p\u003e\u003cp\u003eBecause 18-8524 is specified as the mounting kit for both the starboard manifold (18-1929) and the port manifold (18-1933), a single kit covers the hardware needs referenced by either manifold's catalog listing, simplifying parts ordering for a full manifold replacement job. The kit is compact and lightweight at 0.24 pounds, with overall packaged dimensions of 0.75 x 7 x 22 inches, making it easy to store or ship alongside the manifolds and gasket it is used with.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-8524\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Manifold Mounting Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With Manifold (Starboard):\u003c\/strong\u003e 18-1929\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With Manifold (Port):\u003c\/strong\u003e 18-1933\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Fitment:\u003c\/strong\u003e GM Big Block (V8) 454 cu.in.
